Title: Furnace-inside observation device
Inventor: KAIEDA SUMIO
IPC: F27D21/02
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To observe the state of a high temperature furnace with a simple structure without provision of a cooling function to cool an optical system member by placing the optical system member made of a material whose softening point is higher than the temperature inside the furnace and fixing an optical system in the through-hole of the furnace wall. SOLUTION: When a casing 26 of the in-furnace observation device 10 is inserted to a through-hole 30 of a furnace wall 28, an observed image of a flux line of molten glass is transmitted from an objective section 14a of an optical system member 14 to an eyepiece section 14B. Then a CCD camera 20 of an image pickup device placed at the outside of the furnace picks up the transmitted observation image and displays the image onto a monitor 22. Since the optical system member 14 is made of a quartz glass material whose softening point is higher than an in-furnace temperature and that is optically uniform, no cooling facility to cool the optical system member 14 is required. Since the image of the flux line of the molten glass can be picked up by having only to place the optical system member 14 to the through-hole 28 of the furnace wall 28, the structure of this device is simpler than that of a conventional device.
